What is Apache Stratos?
๏ It is a Platform-as-a-Service (PaaS) Framework
๏ Currently incubating at Apache Software Foundation
๏ A Single Product with Multiple Profiles
๏ Developer Friendly!

Why is this a Framework?
๏ Stratos can be extended to build you own flavours of
PaaS.
๏ Application PaaS (aPaaS), Integration PaaS (iPaaS) etc.
๏ WSO2 App Cloud (WSO2 App Factory) runs on Stratos.
๏ Provides APIs & extensions
๏ Easy to bring your applications to cloud

๏ Leveraging WSO2 Carbon multiple profile support
๏ There are 3 profiles:
๏ Cloud Controller (cc)
